What servicing does my wood burning or multi fuel stove require?

At the end of each heating season, as well having your chimney swept, your stove should undergo an annual service which will include stripping, inspecting and cleaning the appliance. Although this is best carried out for you by a HETAS registered engineer, you can do it yourself by following instructions provided.

Your Stovax retailer should be able to arrange the annual service for you or you can find details of HETAS registered engineers by visiting www.hetas.co.uk.

If you wish to undertake the service yourself, follow these instructions:


Servicing instructions for your particular appliance are given in your Installation and Users Instruction Manual. If you have mislaid this, then you can download or view a copy in our Technical Information section.

  • The following information, however, is given as a general guide:
  • Allow the appliance to cool
  • Remove all the following internal parts – baffle, firebricks, grate and ashpan. Take care handling the bricks as they can become fragile after a period of use.
  • Vacuum any remaining ash and debris from inside the appliance (Stovax offer a filter/collection attachment for vacuum cleaners using dust bags – Ashclean)
  • Clean the internal surfaces using a wire brush and scraper as required. Vacuum and resulting debris
  • Clean the grate and any grate parts with a wire brush and check for any damage, replace any damaged parts
  • Clean the firebricks with a soft brush, check the bricks and although some surface wear and tear will occur with use, damaged or broken bricks should be replaced
  • Re-fit all cleaned internal parts and replacement parts
  • Remove the glass from the door and discard old or worn rope seal
  • Clean old glue from the groove which held the rope seal
  • Replace the rope seal, gluing into place with a thermic seal adhesive, and re-fit the glass
  • Lightly oil the door catch mechanism and hinge pins
  • To refresh the exterior look of your stove or fire, aerosol paint or colloidal black cleaner is available for most painted finishes. Enamelled surfaces should only be cleaned with a lightly dampened, soft cloth only.

Can I install a stove or fire in a Smoke Control Area?

If you live in a town or city, the chances are that you live in a Smoke Control Area.

To meet the smoke emission standards for these areas, you will need to burn smokeless fuels only on a multi fuel stove or fire, or you can burn logs on a wood burning or multi fuel stove or fire that has been approved by DEFRA as sufficiently cleanburning to be exempt from the regulations.

Numerous models in the Stovax range are approved to burn logs in Smoke Control Areas and these are detailed on the product pages of this website. To check whether you live in a Smoke Control Area visit www.uksmokecontrolareas.co.uk.

Get further information and details of Yeoman products suitable for use in Smoke Control areas.

Who can install my stove for me?

An experienced, HETAS approved installer should fit your stove. Your Stovax retailer should be able to arrange this for you or you can find details of HETAS registered installers by visiting www.hetas.co.uk.

What is cleanburn?

Cleanburn is a system by which warm air is introduced into the firebox just above the normal height of the fire.

The effect is to allow the combustion of unburned hydrocarbons in the smoke stream. This, in turn, provides not only a ‘cleaner burn’ (i.e. less soot particles going up the chimney/flue and into the atmosphere) but also generates up to twice the heat output from the same amount of fuel.

Furthermore, you will enjoy the sight of even more flames.

How efficient are wood burning and multi fuel stoves?

Today’s stoves are more efficient and technically advanced than those manufactured only a few years ago so efficiencies up to 86% are now possible.

For example, a stove with a net fuel input of 6.5kW and an output rating of 5kW is 77% efficient. With a very few, particular exceptions, the figures for all Yeoman Stoves have been independently verified by CE and HETAS approval systems.

Also do not forget that, unlike an open fire or hearth, a stove has airtight doors and a sealed flue so it will not draw heat from other heating sources, such as radiators or electric storage heaters, up the chimney. This means the stove can conserve energy even when it is not lit.

What is the difference between wood burning and multi fuel?

Logs burn best on a flat bed of ash, with air for combustion coming from above. Coal and smokeless fuels burn best on a grate, with air entering from beneath the fire and cinders dropping into an ashpan below.

Wood burning models, therefore, have flat fuel beds whilst multi fuel models incorporate grates, but the latter are also designed to allow you to develop a bed of ash upon which to burn logs should you wish.

What size stove do I need to heat my room?

To achieve a relaxing room temperature of around 21ºC when the external air temperature is at freezing (0ºC) you will need approximately 1kW of heat output for every 14 cubic meters of space.

Measure the length, width and height of your room and multiply the three figures together.

For example, a room measuring 7m long by 4m wide and with a height of 2.5m is 70 cu. m. of space. Divide by the sum by 14 and this means you will require a 5kW stove.

However, factors such as the number of outside walls, the size of windows and whether they are double glazed, the age of the home etc, can all influence the heat requirement.

We would always recommend you consult your local Yeoman retailer for expert advice before making your decision.
